Hi, Attached is a patch implementing compiler note references in the *compiler-notes* buffer. I'm sending it here for discussion, not only because it only works in bleeding-edge sbcl (yes, once again breaking all released versions...) but because of some of the violence I've done to slime.el. I'm aware of the badly-factored nature of the current patch, and I promise to fix that, but what worries in particular is the stuff in slime-tree-default-printer: how does it work, and what am I allowed to do there. What I have seems to work currently, but additional newlines (from terpri or (insert "\n")) cause weird stuff to happen -- I don't really understand why, but the " |" things ended up at the bottom, as in <http://www-jcsu.jesus.cam.ac.uk/~csr21/tree-oops.png">. Understanding what's going on would probably enable me to make a cleaner patch...
